Chlorotabanus crepuscularis
29.1872, -82.1401
Field Notes
Description:
A very large, very fat Green Horsefly. About 3/4" long, huge head comprised mostly of eyes. The space separating the eyes signifies a female. (Males eyes meet in the center.)
Only females bite mammals in order to get a blood meal. They are supposedly attracted to CO2, which makes sense- since mammals exhale CO2..
Habitat:
Our yard. "
Notes:
Species name "crepuscularis" comes from the latin "crepusculum", meaning "twilight". Named for the fact that these biting buggers come out at dawn and dusk.
Good to know!
